Irving is projected to miss 3-4 weeks with a left shoulder sprain, the team announced Monday. Irving sustained the injury in the third quarter of Sunday's game against the Toronto Raptors and will undergo treatment and rest to heal the shoulder.

Officially, it's a sprain of the acromioclavicular, a joint at the top of the shoulder, according to emedicine.medscape.com.

Unofficially, this could put an end to Irving's season. He recently missed three games with a hyperextended right knee. Of Cleveland's 63 games, Irving has missed 14, including 11 with a non-displaced fracture in his left index finger.

Irving also sustained a broken right hand during the Cavaliers' summer league in July and sustained a fractured bone in his jaw in December.

Last season, Irving missed 14 games with a concussion and a right shoulder sprain. He also missed 26 of 37 games during his freshman season at Duke in 2010-11 with an injured right toe.
